Daily Questions Week of Jan.27- Jan. 31 Jan. 27- In order for a fish to see a bug just above the surface of the water, light travels from the insect through the air and crosses into the water until it reaches the fishes’ eye. Which statement is true regarding the light wave as it travels? A.It will bend as it hits the water because it slows down B.It will bend as it hits the water because the water particles move slower than air C.It will travel straight from the bug to the fishes’ eye because that is the most direct path D.It will travel straight from the bug to the fishes’ eye because it will continue to travel at the speed of light
Jan. 28 There are two basic finishes to most paper, glossy and matte. A glossy finish is used to produce a higher finish quality, for instance the cover of a magazine. A matte finish is used to produce a softer finish with less glare, for instance your notebook paper. If you were to compare both of these surfaces under a high-powered microscope, how would they differ? A. The matte surface would be much rougher B. The glossy surface would contain more fibers of white paper C. The glossy surface would be still, while the matte surface would appear to move slightly D. The matte surface would be solid, while the glossy surface would appear to have small holes
Jan. 29 You are sitting on the edge of a pool with your legs in the water. As light waves pass from the pool into the air, it looks like your legs are not attached at the knees where they meet the water. This is because light waves ________ when they pass from one medium to another. A. are amplified B. diffract C. reflect D. refract
Jan. 30 Which of the following would reflect rather than refract light? A. Magnifying glass B. Mirror C. Prism D. Lens
Jan. 31 As light waves pass through openings in a barrier or around the edges of an object, the waves change direction or A. are absorbed B. diffract C. reflect D. refract
Answer Key: Jan. 27- A. Light waves slow down as the hit water, causing the light to refract, or bend. Jan. 28- A. The matte surface would be rougher, glossy surface used for higher quality Jan. 29- D. Light waves refract (bend) as they travel from one medium to another. Jan. 30-B. A mirror reflects light. Jan. 31-B. Diffract. Diffraction occurs when light travels around an object, or through an opening in the object.
